There is a need to improve the technical subject knowledge of the Army physical training instructors and supervisors. The most economical and practical method of providing physical training personnel for the field is through a centralized training institute. Development and research facilities should be centralized to improve development of the Army's physical readiness program. Many of the injuries sustained during physical training because of improper exercise are avoidable and could be prevented by qualified school-trained physical training instructors in the field. Current unit A and R programs do not fulfill their potentiality in small units due to a lack of properly trained instructor/supervisory personnel in the field. Many physical training personnel in the field are not adequately prepared to assume responsibility for planning, supervising and leading physical training activities.
